Mildly modded skyline GTT as daily driven car?

[Dr.D]

a friend bringing in NISTUNE , a direct replacement for gtt ecu but fully programmable. can use on gtt auto.

hi fellow enthusiasts....

its me again... been looking for a good GTT and damn, it really takes a lot of time and effort...

as i read from the forums, it mentioned that an AUTO GTT cant take Apexi PFC as replacement ECU... anyone can verify this? and if the car were to be pumped RON95, the stock ECU will automatically retard itself incase of knocking?

the car that i am looking at is currently a Auto GTT, only mods will be the HKS open pod, straight flow exhaust and a FATT Timer... kekeke.... since the previous MT GTT didnt materialised, and taking all considerations, decided to go for AT.... wifey need to drive as well... no choiice... hahahah

pls advise!! thanks!

PowerFC won't work with auto cars as mentioned by the rest. Namely because I think auto ECUs have to be able to manage the countless points at which the gearbox changes up or down and then retard ignition timing accordingly. Basically replicate a manual driven car with foot off throttle when clutched in to change gear and mimic that in addition to managing the tuning aspect of the car's engine. And for that the PowerFC isn't capable I guess.

I can't really say I know much about tuning but someone here could. I have a few books on tuning but they ran away from home :hmmmm:

may i know how to obtain this NISTUNE?

well u cant either buying from ausi nistune, or go to UMS puchong to order

i use GTT manual daily..around RM50 per week of 40km daily driving..standard everything..the key is not to go to "boost rpm" (when ur turbo start spooling) everytime

for daily driving i used ron95 no knocking whatsoever..some people say we need to avoid it bt i think Rb25 can use ron95 and above in standard form.

ohh btw, skylines have big fueltank

How come JB monster drink only 50hengget per week??? Cabutttttttt!!

Please avoid RON95. Crap fuel we getting here. Equivalent to RON92. We tried tune a car for RON95, it is possible but can really see the knock values higher than expected.

I drive a quad plate and although it's not a daily driver, I don't see why it can't be driven daily if need to. I've driven it to work and back a couple of times including after office traffic jams and stuff (Klang to UMMC) without breaking a sweat.

It's an OS Giken quad plate which is as light as OEM I might say. Had an HKS twin plate which was a bitch to drive in traffic jams though others may be okay with it.

So it depends on the brand/type of clutch as well as how u drive.

It is relatively cheap to daily drive a performance car (cheap means bearable, though u obviously can't compare it to a Myvi laa..). And like what V-Spec has mentioned, it gets expensive if u start to mod it.

Erm.. Why would u have a twin plate clutch? Buying a modded car I suppose? Be prepared to spend some for wear & tear mantenance.. Which may be just the regular fluid changes (engine, differential, gearbox oils, radiator fluids etc) or could include more expensive things like tyres, brake pads, engine overhaul etc).

I'd suggest those who intend to buy these cars to get a stock standard car if possible as maintenance cost would be fairly minimal and u don't get the bug to mod that quickly (maybe).

Good luck in ur search and hope u enjoy ur ownership of the Skyline. Join us on drives.. Which is almost weekly thanks to the cravings of our Ketua Darjah..

You're using quad plate? Never knew that bro. Can test around the carpark next time? Someone offered me a quad plate sometime back but I didn't dare buy it because even with triple plate my cousin broke his box what more quad plate. Rather run twin plates, and let the clutch take all the abuse rather than the box. But still curious how it drives lah.

i have to agree on that

 

[ek_elleh]

can rb26 with apexi PFC use ron95??

 

[reccaoji]

i have to agree on that

i thought skyline got this knocking sensor to prevent from knocking

When I bought the car, the owner informed me that it was running a triple plate HKS sourced and installed at Links.

When the engine was out, I had a look and it turned out to be an OSG quad plate.

Interestingly though, the pedal feel was not much heavier (lighter in fact..?) than the Exedy twin plate that I had in my previous car. I was happy to run the quad plate but the friction plates were getting really worn already.

Sourced a relatively new ORC twin plate from V-Spec (via gobiz.. thanks gobiz! :top:) and it is awesome (samurai sword sounding and very light on the foot). Plus I think ORC is much more gentle to the drivetrain than the OSG quads.

Though BR says the pedal is damn heavy for his liking (compared to the stock R34 clutch)..

Can. But dont dream of getting high hp. I bet you would get lower bhp than standard spec!!

I think most if not all RB engine has knock sensors... if not mistaken it will retard ignition or something when it sees knock..so reduce power...

But I think for tuned engines maybe it can't do this quick enough to prevent serious knock and subsequent damage...not sure...

It was sourced by V-spec and JDM Autolink...at a FANTASTIC price too

Japanese fuel is ron99 right? What is the equivalent here?

 

[Dr.D]

all rb got knock sensor, but does ur ecu have the knock map to retard timing map when knocking. ori ecu got knock map, after market dont have.. well some has but not all..


regarding ron 95, even in uSA the gtrs are running ron 91, i myself am running ron 95.. might not perform as good as ron 97 but already maxing out air flow at 1 bar of my rb26.. its all about tuning nowadays.. im sure the air flow doesnt max out at 280 bhp only

 

[shark79]

in states gtr on lower ron running mega bhp

Hehe .... Thank you guys. :top:
